Hello I just installed my new system last night...
This morning when i got in the car to go to work the heater was blowing but no heat just cool air and i notice that my airbag light was on..
Do i need to unplug the battery for a little bit and then try it again?
please help it's getting cold out there .....

 

Did you happen to disconnect the heater valve cable under the dash?

 

Yes but plug it all back in

 

Check whether or not the heater valve on the firewall under the hood properly opens and closes when the heater lever is operated.

Also check whether the coolant level in the radiator and reservoir is full. If all seem fine, then another possibility is that the thermostat is stuck closed.

 

Yeah its werid it work before i put the stuff in the car and now it won't but ill check again thank

 

Yo I just got home from work and the darn thing works ... HOT lol
Thanks for yalls help ,,,

 

Do check your coolant level to be sure it is OK. Low coolant can cause intermittent heat. Wait for the engine to get COLD then take off the radiator cap and confirm the radiator is completely full.

 

I think he meant to say stuck open a thermostat stuck closed will cause overheating, a thermostat stuck open will not allow the motor to reach operating temp.

 

TheJGB3 is correct.
